Algebra.Com's Answer #416013 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! If you're considering complex roots, then it has 3 complex roots according to the Fundamental Theorem of Algebra (notice how the degree of this polynomial is 3).\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "And it turns out that graphing it gives us this\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "and we see 3 x-intercepts (which means that there are 3 roots) \n" ); document.write( " |
